ok... i've written a couple items on this, though this should be the question to ask .. for you that have had cards for over 3 months.. have you had any issues?

the pny is rated highest, followed by kingston and sandisk (neck / neck). transcend is not much lower, but the complaints seem to be w/ the card failing after a period of use. anyone have issues to report before i shell out some bucks on one..

Thx ..

First off, how and where did you get those reliability ratings?

Second, both PNY and Kingston use multiple sources for their SD and SDHC cards. And I found that the PNY-branded cards sourced from Toshiba barely met their labeled Class 4 specs, based on my real-world write testing in a very fast card reader.

Great question.. My method was "unscientific" in that I went to any site that I could find that allowed ratings posted by users and compiled the results. PNY came out ahead in this method. This method will result in users using cards in a way they were not intended, using in cameras, etc. hence, asking the question here. given your knowledge, which card would you recommend? Quote:

I bought a second hand Transcend 16GB SDHC from the FS forums here on HeadFi that has 14.9 GB space on it that has been 100% reliable. I only use it in my Cowon D2.

All else equal, the card that sells the most will have the most failures.

Reliable under what use?

Stick it in your player, gradually load it with music, then read-only from there on?

Use it as a portable disk drive? (lots of moving from one slot to another, and all day read/write cycles)

my intention.. have a card that is gradually filled w/ music using an external reader. won't have much movement (not a portable drive) i don't agree w/ your logic on the most sold = most failures. 1000 cards at a 1% failure rate would result in 10 bad cards.. 100 cards at 10% failure would result in 10 bad cards..

Same conclusion. (Assuming they all get on here and complain) you see 10 tales of failure either way, but that alone doesn't tell you that the best seller is 10x a reliable.

Excellent point.. I didn't want to assume 'more expensive' = 'higher quality' .. very good point, though.. Quote:

i'm very happy with my Patriot 16GB. The only time it ever failed was when I stuck it in a non SDHC reader, and that was fixed after a re-format.
